To aZZ whom it may concern:
Be it known that I, LILLIAN ADAIR, a subject of the King of Great Britain, residing at Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and usefulllmprovements in Metatarsal- Arch Supports, of which the following is the specification.
My invention relates to improvements in metatarsal arch-supports, and the object of the invention'is to devise a support for the forward ends of the bones extending rear wardly from the metatarsal joint, thus preventing the ailment commonly referred to in the medical profession as Mortens toe.
My invention consists of an insole provided on its lower face with a pad ofresilient material, of preferably, semicircular shape and so situated as to raise up and support the forward ends of the bones above referred to, all as hereinafter more particularly described'and illustrated in the accompanying drawing in which Figure 1 represents a longitudinal section of a boot, and a foot therein, showing my insole and pad inserted in the boot.
Fig. 21s an inverted plan view of an insole and pad constructed according to my invention, and
Fig. 3 is a cross section of my insole and Like characters of reference indicate corresponding parts in the different views.
l is a boot, and 2 is an insoleprovided on its lower face with a pad 3 of semi-circular shape constructed of resilient material, the curved edge of the lower surface being beveled or rounded otfas illustrated, and the forward edge inclining rearwardly from the inner to. the outer end of the same as shown in Fig. 2. 4 is the foot, and 5 is the meta tarsal joint. 6 are the rearwardly extending bones, and 7 are the forward ends thereof.
ln'the ailment above referred to, the for ward ends 7 of the bones 6 drop and the "person thenwalks practically on these for- Specification of Letters Patent.

inclined rearwardly as shown in Fig. 3 in order to conform with the inclination of the metatarsal joint, and it is not beveled or rounded but left vertical in order to impart the maximum pressure at the required point. An insole provided with a pad constructed according to my invention will also, by'restoring the perfect articulation of the metatarsal joint, prevent callouses forming on the ball of the foot immediately beneath the metatarsal joint, which is due to pressure.
From the above description it will be seen that a device constructed according to my invention will be of great value, and will relieve considerable suffering. Moreover, it
is simple to construct and can be put on the market very cheaply,and there is no appreciable addition in weight which is the case with metallic supports atpresent in use. What I claim as my invention is I 1. In a metatarsal arch support, the com.-
bination with an insole, of a pad of resilient material suitably secured to the underneath side of the sole and having a vertical forward edge inclined laterally in a rearward direction from its inner to its outer end in conformity with the axes of the respective metatarsal joints, the pad situated on the insole so that its vertical forward edge exerts pressure on the first metatarsal bones immediately in rear of the metatarsal joints.
2. In a metatarsal arch support, the combination of an insole, of a pad of resilient material having a vertical forward edge, said pad being suitably secured to the under side of the insole and so situated that its vertical forward edge exerts pressure on thefirst metatarsal bones immediately in rear of the metatarsal joints.
3. In a metatarsal arch support, an insole, and a pad of resilient material of semi-circular shape, the arc of the semi-circle at the rear, said pad raising the forward ends of.
the bones extending rearwardly from the metatarsal joint.
4. In a metatarsal arch support, an insole and a pad of resilient material of semi-circular shape, the arc of the semicircle at the rear, the curved edge of the pad beveled or rounded off, and the forward edge vertical and inclined rearwardly from the inner to the outer end, said pad raising the forward ends of the bones extending rearwardly from the metatarsal joint.
LILLIAN ADAIR.
